trial of caldolor for treatment of pain in post-operative adult patients

Conditions: Pain

Summary: the primary objective of this study of caldolor (iv ibuprofen) administered to post-operative hospitalized adult patients every 6 hours for 48 hours is to determine the efficacy of caldolor compared to placebo for the treatment of post-operative pain as measured by reduction in the requirement for the narcotic analgesic, morphine, post surgery
